Title: Material height determination system - has two photoelectric receivers mounted on endless belt with drive which can operate height indicator
Inventor: LEIFELD FERDINAND DIPL ING
IPC: D01G7/10
Filed: 1978-04-24
Abstract: The system determines the height of material in a shaft, fibre bale etc., using a photo-electric system with sender and receiver. A drive or feed mechanism is controlled by the material height. Two or more receivers (2, 3) are moved in the vertical direction, and the impulses from both actuate the drive moving them when the end of the material is outside the space between them. The drive can also actuate a height indicator. The sender (1) can work with two movable receivers coupled to a control unit (4), in turn connected to a drive or feed mechanism (10).

Title: Red grape juice fermentation vat - keeps husks suspended by descending circulatory current
Inventor: VESELIC MIRAN PROF
IPC: C12G1/02
Filed: 1978-04-25
Abstract: In a fermentation process of mashed red grapes, the husks are kept in uniform distribution in the grape juice by a descending circulatory current which counteracts teh buoyancy forces acting on the husks. These are therefore kept surrounded by fluid on all sides with the greatest possible diffusion. The result is an intensified contact between husks and juice without damaging the husks, so that the treatment is completed in a shorter time and becomes more economical.

Title: Reconditioning double glazing - by drilling holes in spacer, venting and filling with fresh gas
Inventor: REINECKE KARL-OTTO
IPC: E06B3/677
Filed: 1978-05-23
Abstract: Insulating double glazing, in which the gap between the panes is filled by a gas with a lower conductivity for heat and sound than air can deteriorate after some years when leakage losses have occurred. An appliance has been designed which can be clamped to the panes by suction cups and carries a drilling head. One or two holes are drilled in the spacer between the panes or in the margin of one of the panes and the air gap is vented; fresh gas is then filled in and the holes are sealed hermetically. Double glazing can thus be reconditioned many times; it saves having to replace complete leaky double glazing panels by new ones.
Patent DE-2825948-A1 (DE)
Title: Power driven typewriter ribbon fork lifting mechanism - has rotary cam with peaks corresponding to fork rest position
Inventor: THEILEN ROLF
IPC: B41J35/10
Filed: 1978-06-14
Abstract: The lifting mechanism is for the ink ribbon fork of a power-driven typewriter or similar machine. The stroke varies with successive typing operations. A drive shaft turns through one revolution with each operation, being followed by a drive making only part of a revolution and incorporating a cam with difference humps corresponding to the angles through which it turns. A roller-ended lever, spring loaded against the cam, transmits the stroke to the fork. The cam peaks (10) all of the same radius, correspond to the rest positions of the fork (22), and the different humps (11, 12, 13) determine the fork stroke. The spring (15) of the roller-ended lever (14) supplements the motor starting torque.

Patent DE-2829779-A1 (DE)
Title: Selectively absorbent interference layer for solar energy converter - using layer of silica contg. gold particles reducing reflection of solar rays
Inventor: BRUENGER WILHELM DR
IPC: G02B5/28
Filed: 1978-07-06
Abstract: The interference layer (1) reduces the reflection of the incident solar radiation so high absorption is obtd. But layer (1) does not markedly impair the high reflection of an underlayer (3) in the infrared region. Layer (1) consists of a thin dielectric, esp. SiO2, in which metal particles are embedded, the particles being small w.r.t. the wavelength of the radiation being absorbed. The particles are difficult to oxidise, and are esp. gold. Instead of SiO2, other refractory oxides, e.g. Al2O3 or MgO, may be used. The thickness of layer (1) pref. results in max. absorption in wavelength region 0.2-2 mu m; and the concn. of Au in layer (1) pref. exhibits a gradient. The absorber is pref. covered with Au, followed by simultaneous deposition of the SiO2 (1) and Au. Max absorption is achieved in wavelength region 0.2-2 mu m, but the high reflection of the Au underlayer (3) in the IR is only slightly impaired; and the working life at operating temps. up to 500 degrees C is greatly increased.
Patent DE-2830988-A1 (DE)
Title: Limb prosthesis with load-bearing surface on which limb stump rests - has silicone rubber padding with protective textile cover to ease blood circulation
Inventor: BAUERFEIND HANS B
IPC: A61F2/80
Filed: 1978-07-14
Abstract: Limb, esp. leg. prosthesis has a supporting surface for the end of the stump of a wearer's natural limb, of the contact-shaft type. The supporting surface is provided with a padding of essentially incompressible but deformable material, suitably a silicone rubber. The silicone rubber is coated, at least on that surface on which the limb stump bears, with a protective layer of textile, esp. natural, fibres. The claimed construction facilitates blood circulation through the end of the natural-limb stump (which is in many cases heavily scarred thus presenting risk of poor circulation).
Patent DE-2836820-A1 (DE)
Title: Ventilating duct for sterile operating zone - has sloping sides with vanes forming outer flow around main flow from central grid
Inventor: DUVLIS ZINON DR MED
IPC: A61G13/00
Filed: 1978-08-23

The sloping sides also incorporate sloping slats which guide the air flow outwards. This forms an auxiliary air curtain outside the main central flow. The central region is divided into two equal chambers by a division plate. Air distributor tubes through the grid have side opening discharging into these two chambers and end openings for discharging against the rear of the sloping slats.

Title: Do:cyclo-pentyl:ene-(2,2'-bis(4-alkyl-6-tert-butylphenol)) prepn. - by reacting 4-alkyl-6-tert.-butyl-phenol with dicyclopentadiene in presence of specific solvents and boron fluoride catalyst
Inventor: MUELLER ROLF DIPL ING
IPC: C07C37/14
Filed: 1978-10-04
Abstract: Prepn. is claimed of dicyclopentylene/2,21-bis (4-alkyl-6-t-butylphenols)/of formula (I) (where R1 is t-butyl and R2 is Me or Et), by reacting 1.5-2.5 moles of cpd (II) with 0.8-1.2 mole dicyclopentadiene at 20-120 degrees C in the presence of an organic solvent and BF3 or its complex as catalyst. The improvement consists in using as solvent: (a) an aromatic solvent which, under reaction conditions in presence of the catalyst, does not undergo transalkylation with the t-butyl gp. of (II) and/or (2) a non-aromatic solvent which, under the reaction conditions, does not have nucleophilic properties which strongly reduce or completely suppress the catalyst efficiency. The reaction is effected under anhydrous conditions. (I) is an antioxidant for organic substances eg natural and synthetic rubbers, polyolefins, vegetable and mineral oils etc. The process occurs in one step and gives (I) in high yields and in a non-polymerised state.
Patent DE-2847231-A1 (DE)
Title: Insulating system for chimney stack - uses tension in rope to control speed with which bell is pulled up chimney to smooth material against wall
Inventor: ROTH PETER
IPC: E04F21/14
Filed: 1978-10-30
Abstract: The insulating system covers the inner surface of the chimney by coating with an insulating material introduced from above and compressed with the help of a vibrating bell. The bell is attached to the lower end of a rope (or cable) and pulled up the inside of the chimney thereby compressing the insulating material against the inside of the chimney. The magnitude of the tension in the rope is measured and used to control automatically the speed of the motor-driven winch pulling the bell up the chimney and/or the rate at which the insulating material is fed into the chimney. This control is continuous and maintains constant tension in the rope.

Title: Water purificn. in filtering tank - contg. reduced pressure space above filter bed to facilitate gas and volatile material discharge
Inventor: KLEIN HANS-ULRICH ING GRAD
IPC: C02F5/00
Filed: 1979-08-30
Abstract: Water purificn., esp. for removing Fe and Mn, for nitration, deacidification, dehydrosulphurisation and for removing volatile organic materials, takes place in a filtering tank to which the crude water is charged below the filter. Novelty consists in (i) maintaining a space situated above the filter, in filtering tank, at reduced pressure, and (ii) discharging gases formed during filtration, e.g. CO2, H2S, N2 and O2, and also volatile organic cpds. from the reduced pressure space. Filtration plant is claimed. Space above the filter bed in filtering tank is kept at reduced pressure by vacuum pump. Reduced pressure space facilitates the discharge of gases and volatile materials to be removed.
